The Big Bang Theory

The original concept of the Big Bang theory states that the universe materialized through a process called singularity at the start of the universe known as time zero. It describes the process taking place 0.0001 seconds after the start of time, "the birth of creation". Upon birth the temperature of the universe was 1,000 billion degrees Kelvin with a density containing nuclear matter. The density of the environment at this point was over 1000 that of water, 1014 g/cm^3.

The universe was under extreme conditions, the resulting radiation produced so much energy that the photons became interchangeable with other particles. These photons generated pairs of particles and antiparticles which obliterated each other resulting in the construction of energetic photons producing a continuous exchange of energy. This is where Einstein's equation of E=mc^2 links to this instance. Basic interactions poses minor irregularities, these irregularities formed slightly more particles that antiparticles, approximately one in a billion more particles than antiparticles.

The universe would cool after the photons no longer contained the energy required to supply additional particles. The paired particles and the antiparticles eradicated one another and the one in a billion particles remaining became stable matter, after settling. 0.01 of a second after time zero the temperature cooled down to 30 billion K. After 13.8 seconds the temperature was down to 3 billion K. Upon reaching 3.02 seconds had dropped to 1 billion K, 70 times hotter than the core of the sun at present day. At 1 billion K the nuclei of helium and deuterium were able to be created and conjoin in spite of collisions with other particles.

Four minutes after time zero reactions occurred the neutrons in the helium nuclei remained locked. The acme finished with less than 25% of the nuclear material rehabilitated into helium. The remains left behind were lone protons, hydrogen nuclei. This info is described in 1940 by Gammow and Fred Hoyle in the 1960's. Slightly over 30 minutes after time zero almost all of the electrons were annihilated by the positrons. Once again one in a billion remained. The left over established the proper background radiation and the temperature was now down to 300 million K. The density of the atmosphere at this time being only 10% that of water. This temperature would not permit stable
